Therefore, the directions and positions used are used to explain and understand the present invention, but not to limit the scope of protection of the present invention.

[0025] like Figures 1 to 5As shown, an embodiment of the utility model is a barrel anti-drop buckle, which is used to lock the connection between the barrel 1 and the cone bucket 2. The side wall of the barrel 1 is provided with a fixed block 3, including a hook 4, a handle 5 and a buckle seat 6 installed on the fixed block 3, and two hinge seats 7 are extended from the side of one end of the buckle seat 6. The handle 5 is a U-shaped structure and the two ends of the handle 5 are rotatably connected to the two hinge seats 7 by rivets 8. A lock core 9 is provided in the middle of the handle 5, and the two ends of the lock core 9 are rotatably connected to the two ends of the handle 5 respectively. The hook 4 includes a hooking section 10 and an adjusting section 11, and one end of the adjusting section 11 is provided with an external thread 12, and the lock core 9 is provided with an internal thread through hole 13 adapted to the external thread 12, and the thread length of the external thread 12 is greater than the thread length of the internal thread through hole 13, and the hook 4 is threadedly connected to the lock core 9. The utility model has a buckle adjustable structure, that is, the external thread of the hook is threadedly connected with the internal thread through hole of the lock core, and the telescopic position of the hook can be changed by adjusting the relative position of the external thread. The thread length of the external thread is greater than the internal thread through hole, which can not only ensure the strength of the thread connection but also provide a large adjustable range, and can meet the locking requirements of barrels and cone buckets of different sizes, and has the advantage of a wide range of applications. The utility model has a delicate structure and reliable operation; it adopts an assembled structure, which is easy to disassemble, install, and maintain; it is suitable for occasions where it is frequently opened and closed; it is simple to operate, easy to adjust, and improves efficiency.

[0026] The utility model also includes a connecting component, which includes a sleeve 14 and a turntable 15. The turntable 15 is located between the hooking section 10 and the adjusting section 11. The end surface of the turntable 15 is provided with at least one mounting hole 16. A first threaded member 17 is installed in the mounting hole 16. The turntable 15 is threadedly connected to the hooking section 10 through the first threaded member 17. The sleeve 14 is sleeved on the outside of the turntable 15. The side wall of the sleeve 14 is provided with at least one second threaded member 18. The sleeve 14 is threadedly connected to one end of the adjusting section 11 away from the external thread 12 through the second threaded member 18. The inner edge of one end of the sleeve 14 away from the second threaded member 18 is contracted to have a limiting portion 19 with an inner diameter smaller than the turntable 15. The turntable 15 is located between the limiting portion 19 and the second threaded member 18 and is rotatably connected to the inner wall of the sleeve 14. The hooking section 10 and the adjusting section 11 are connected together through the connecting component. Through the above structure, that is, the hooking section and the adjusting section are connected together through the connecting assembly, and the turntable connected to the hooking section through the first threaded member can form relative rotation with the adjusting section. The hooking section can not only rotate and retract following the external thread but also can rotate horizontally to adjust the direction independently, thereby ensuring that the hooking section can face the cone bucket and realize the function of snapping the cone bucket and the material barrel. It has the advantage of more precise adjustment of the telescopic position of the hook. The adjusting section limits the turntable through the sleeve connected to the second threaded member, and prevents the turntable from falling off through the limiting part.

[0027] The inner edge of one end of the mounting hole 16 away from the hooking section 10 is provided with an inverted bevel 20. The inverted bevel guides the first threaded member to extend into the mounting hole, which has the advantage of quick assembly.

[0028] The connection assembly further includes a cushion block 21, which is located between the sleeve 14 and the adjustment section 11. The side wall of the cushion block 21 is provided with an assembly hole for the second threaded member 18 to pass through. The cushion block improves the structural strength of the connection assembly and prevents debris from entering the sleeve.

[0029] A convex ring 22 is provided on one end surface of the rotating disk 15, and a ring groove matched with the convex ring 22 is provided on the cushion block 21. The rotating disk 15 and the cushion block 21 are abutted against each other through the convex ring 22 and the ring groove. One end of the rotating disk 15 abuts against the limiting portion 19 and the other end abuts against the cushion block 21. The rotating disk cooperates with the ring groove of the cushion block through the convex ring, and the cushion block guides the rotating disk to prevent the hooking section from tilting.

[0030] The side wall of the convex ring 22 is provided with a tapered surface 23. Through the above structure, the tapered surface can resist radial external force, further prevent the hooking section from tilting, and the rotation of the turntable is smoother and more labor-saving.

[0031] The angle between the conical surface 23 and the horizontal plane is between 45° and 60°. In this embodiment, the angle of 55° can provide a greater degree of resistance to radial external forces, further ensuring the smooth rotation of the turntable.

[0032] The outer edge of one end of the rotating disk 15 near the limiting portion 19 is provided with a rounded corner 24. When the hooking section is in the engaged working state, the rotating disk is pulled upward by the hooking section to be tightly against the limiting portion, and the rounded corner prevents the rotating disk from getting stuck and unable to rotate.

[0033] The working principle of the utility model is as follows: the handle is turned to move the hook to the top of the edge of the cone bucket, and the hook is brought close to the conical surface of the cone bucket, and then the handle is turned in the opposite direction to buckle the hook into the groove on the edge of the cone bucket, and the buckling is tightened to realize the anti-loosening function between the cone bucket and the material barrel. According to the different specifications of the material barrel and the cone bucket, the required height of the hook is different. Before the hook is buckled into the groove on the edge of the cone bucket, it can be freely adjusted within the limit range of the threaded connection between the hook and the lock core, and then the direction of the hook holding section is rotated separately in combination with the connecting component to accurately adjust the suitable buckling height of the hook.

[0034] like Figure 6 As shown, it is another embodiment of the utility model, the hook holding section is replaced with a semicircular arc shape that better fits the arc surface of the groove on the edge of the cone bucket, thereby increasing the contact area of ​​the hook and further improving the sealing performance of the buckle.

[0035] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
